Application of a one‐dimensional spray model to teach diffusion flame fundamentals for engineering students

Abstract

This study presents the application of an existing interactive application for teaching spray dynamics in engineering degrees. The model is based on spray momentum conservation and can be used to evaluate both fuel-air mixing characteristics in inert conditions as well as diffusion flame performance once combustion takes place. During a dedicated computer-lab session, the students perform parametric studies regarding the influence of the nozzle outlet diameter, the combustion chamber density and the spray cone opening angle on the mixing process, characterized by the maximum stoichiometric length. Later on, the effect of the combustion reaction on the mixing field is evaluated.The results are analyzed taking as a reference to the theoretical development made by Spalding and Schlichting for diffusion gas jets. The outcomes of several years using this technique are reported. K E Y W O R D Scombustion, educational tool, engineering teaching, practical session, spray

Case study‐based learning using a computational tool to improve the understanding of the jet engine cycle for aerospace engineering degree students

“…Minichiello et al [22] presented a mobile-based particle image velocimetry tool, concluding that it helped to increase students' engagement. García-Oliver et al [11,12] used Computer-Aided Learning techniques in combustion-related topics, highlighting benefits in the learning processes by the students.…”

Integration of recent developments in transient heat conduction and mass transfer for solid sphere into teaching

“…Unfortunately, these two representative studies concerning the teaching approaches of the heat transfer course failed to discuss whether the achievements of the subject matter were incorporated. As the application of the first factor was focused on a research scholarship, it was achieved that the level of understanding reached by the combination of the theoretical work in the classroom and the use of the spray model for research purposes was previously developed, by the students’ reports [11]. An opportunity to integrate academic research into teaching became the actual motive for producing practical sessions of spray dynamics in a computer lab where the students implemented a variety of parametric studies to comprehend the subject by a computer‐aided learning method.…”
